ABSTRACT:
A filter cartridge is provided with an end cap and a lock ring which capture a filter element therebetween on assembly and which include projections extending beyond the outer surfaces of the end cap and the lock ring. The application of heat to the projections causes the material of the projections to fuse together and provide a leak-proof seal between the end cap, the lock ring and the filter material.
